Nkhani - Kodi payipi ya PTFE imagwiritsa ntchito chiyani

Chiyambi:

Chitoliro cha Polytetrafluoroethylene (PTFE) ndi chinthu chogwiritsidwa ntchito m'njira zosiyanasiyana chomwe chingapereke ntchito zosiyanasiyana m'mafakitale osiyanasiyana. Chimapangidwa pogwiritsa ntchito njira yotulutsira phala. Chitoliro cha PTFE chopangidwa ndi phala chimasinthasintha. Chimatha kupanga mapaipi a PTFE okhala ndi mainchesi amkati ang'onoang'ono ngati 0.3 mm mpaka 100 mm komanso makulidwe a khoma ang'onoang'ono ngati 0.1 mm mpaka 2 mm.payipi ya PTFEIli ndi kukhazikika kwabwino kwa mankhwala, imatha kupirira ma asidi onse amphamvu, ma alkali amphamvu, ma oxidant amphamvu, ndipo sigwirizana ndi zinthu zosiyanasiyana zachilengedwe. Itha kugwiritsidwa ntchito nthawi zambiri mkati mwa -60℃～+260℃, yokhala ndi kukana dzimbiri kodalirika komanso kwabwino kwambiri. Imatha kunyamula mpweya wamphamvu wowononga ndi madzi pa kutentha kwakukulu. Kuphatikiza apo, ikagwiritsidwa ntchito pa kutentha kwakukulu kwa 260℃ kwa maola 1000, mawonekedwe ake amakaniko sasintha kwenikweni. PTFE ili ndi chinthu chotsika kwambiri cha friction, ndi chinthu chabwino chotsutsana ndi friction, chodzipaka chokha, static friction coefficient yake ndi yocheperapo kuposa dynamic friction coefficient, kotero bearing yopangidwa kuchokera pamenepo ili ndi ubwino wa kukana koyambira kochepa komanso kugwira ntchito kokhazikika. Chifukwa PTFE si polar, yolimba kutentha komanso yosayamwa. Ilinso ndi kukana kukalamba bwino, yosamamatira komanso yosayaka. Izi sizingasinthidwe ndi ma hoses ena.

Chiyambi chotsatirachi ndi momwe payipi ya PTFE imagwiritsidwira ntchito m'mafakitale osiyanasiyana:

1. Makampani opanga mankhwala

Chifukwa chakuti ali ndi mphamvu yolimbana ndi mankhwala ambiri,Machubu a PTFEndi chisankho chabwino kwambiri mumakampani opanga mankhwala. Kuphatikizapo makampani opanga ma semiconductor. Njira yamakono yopangira ma semiconductor imafuna kuyeza bwino komanso kunyamula zakumwa zowononga (ma acid ndi alkali). Izi zidzawononga kwambiri chitoliro chotumizira katundu posachedwa.

2. Makampani azachipatala

Makhalidwe apadera a mapaipi a PTFE akuphatikizaponso kapangidwe kosavuta kuyeretsa pamwamba. M'zaka khumi zapitazi, machubu a PTFE akhala akugwiritsidwa ntchito kwambiri mu zida zachipatala. Chifukwa cha kuchepa kwa kukangana kwa chubu cha PTFE, izi zikutanthauza kuti pamwamba pake ndi posalala kwambiri ndipo sipadzaphimba kapena kuthandiza mabakiteriya kukula. Pakati pawo, mapaipi amagwiritsidwa ntchito poika machubu, ma catheter, ma pipette ndi ma endoscope. Imapanganso zida ndi zida zosiyanasiyana, monga mapaipi otulutsira madzi, ma ventilator, ndolo, rabala wa apulo, magolovesi ndi minofu ina yopangira. Kuphatikiza apo, zida zambiri zogwirira ntchito zomwe madokotala amagwiritsa ntchito pofufuza za biochemical ya anthu zimapangidwanso ndi zinthu za PTFE.

3. Makampani opanga ndege

Mapayipi a PTFE ndi ma fluoropolymers osayaka moto. Kuchepa kwa kupsinjika kwawo kumawalola kugwira ntchito kutentha kwambiri komanso kupsinjika. Ichi ndichifukwa chake machubu awa amagwiritsidwa ntchito ndi makampani opanga ndege kukulunga mawaya ndi zingwe.

4. Makampani a magalimoto

Mu mainjini a magalimoto, mapaipi amafuta apamwamba opangidwa ndi PTFE amagwiritsidwa ntchito potulutsa mafuta ndi njanji zamafuta. Pakadali pano, mapaipi a mabuleki omwe ali pamsika ndi ma payipi a mabuleki okhala ndi zolumikizira. Malinga ndi mitundu yosiyanasiyana ya mabuleki agalimoto, amagawidwa m'mapayipi a mabuleki a hydraulic, mapaipi a mabuleki a pneumatic ndi mapaipi a mabuleki a vacuum. Malinga ndi zinthu zake, amagawidwa m'mapaipi a mabuleki a PTFE, mapaipi a rabara ndi mapaipi a nayiloni. Paipi ya rabara ya mabuleki ili ndi ubwino wokhala ndi mphamvu yolimba komanso yosavuta kuyiyika, koma vuto ndilakuti pamwamba pake pamakhala kukalamba pambuyo pogwiritsidwa ntchito kwa nthawi yayitali. Pakakhala kutentha kochepa, mphamvu yolimba ya mapaipi a nayiloni imafooka, ngati yakhudzidwa ndi mphamvu yakunja, imakhala yosavuta kusweka. Komabe,Chubu cha Besteflon cha PTFEIli ndi makhalidwe monga kutentha kwambiri komanso kutentha pang'ono, kukana kuthamanga kwambiri, kukana kukanda, komanso kukana dzimbiri, zomwe zimapangitsa kuti ikhale ndi moyo wautali ndipo siifunika kusinthidwa pafupipafupi. Imatha kubweza zofooka za zinthu zina ziwiri

5. Makampani amagetsi

Machubu a PTFE ali ndi makhalidwe abwino kwambiri amagetsi. Ali ndi makhalidwe apamwamba a dielectric constant komanso otsika kutayika kwa zinthu m'ma frequency osiyanasiyana. Chifukwa chake, mapaipi a PTFE amagwiritsidwa ntchito ngati zipangizo zapamwamba kwambiri zotetezera kutentha kwa mawaya ndi zingwe, komanso zinthu zotenthetsera zamagetsi ndi zowunikira kutentha. Mumakampani opanga magetsi, kuti aphimbe mawaya ndi zingwe, mapaipi a PTFE apamwamba amagwiritsidwa ntchito, omwe amatha kupirira kutentha kwambiri ndikuteteza mawaya ku kudula kulikonse. Kuphatikiza apo, machubu awa amabwera mumitundu yosiyanasiyana kuti athandize kuzindikira mawaya m'nyumba kapena ku ofesi.

6. Makampani azakudya

Chifukwa cha mawonekedwe ake osavuta kuyeretsa komanso osamamatira, mapaipi a PTFE polytetrafluoroethylene angagwiritsidwe ntchito mumakampani azakudya. Makamaka, machubu opangidwa ndi PTFE osadzazidwa ndi oyenera chifukwa cha kusalowerera kwawo m'thupi ndipo amatsatira malangizo a US Food and Drug Administration. Chifukwa chake, zatsimikiziridwa kuti sizowopsa zikakhudzana ndi pulasitiki ndi mtundu uliwonse wa chakudya. Chifukwa chake, machubu a PTFE nthawi zambiri amagwiritsidwa ntchito mumakina achikhalidwe a khofi. Kuphatikiza apo, machubu otchedwa spaghetti okhala ndi chipinda chimodzi kapena cha zipinda zambiri ndi machubu otenthetsera amagwiritsidwa ntchito. Zogulitsa za PTFE zimatha kutsukidwa pogwiritsa ntchito njira zonse zachikhalidwe.

7. Makampani opanga nsalu

Kusamutsa mankhwala m'mapaipi omwe amagwiritsidwa ntchito mumakampani opanga nsalu kungayambitse dzimbiri. Chifukwa chake, pofuna kupewa vutoli, chubu cha TPFE chimagwiritsidwa ntchito, ndipo chophimba cha PTFE chimapangidwa pa roller ya nsalu.

Makampani Osindikiza a 8.3D

Mu kusindikiza kwa 3D, ulusi uyenera kusamutsidwira ku nozzle yosindikizira yomwe iyenera kuchitidwa kutentha kwambiri. Popeza PTFE chubu ili ndi kutentha kwakukulu komanso mawonekedwe osamamatira, zimathandiza kusuntha mosavuta zinthuzo kuchokera ku nozzle, kotero ndi polima wofunika kwambiri mumakampani osindikiza a 3D.

Kapangidwe ka PTFE kosakhala ndi alkaline kamalola kuti kagwiritsidwe ntchito m'makampani opanga mankhwala, komwe kusamutsa madzi ofunikira kwambiri kumachitika kawirikawiri. Zhongxin Fluorine plastic Industry Co., Ltd. Yakhala ikugwira ntchito yopanga mapayipi apamwamba a PTFE kwa zaka 16.
